After scouring posts in these forums, watching a few youtube videos, I’m not exactly sure what I’m doing that is not allowing my 433 Mhz devices to be discovered by MQTT despite them showing up in the logs.
Currently I’m using rtl_433 (next) with the following YAML config (provided by Chat GPT):
rtl_433_conf_file: ""
retain: false
frequency: 433920000
protocols: []
devices: []
input_args:
- "-f 433920000"
output_args:
- "-F"
- json
- "-F"
- >-
mqtt://192.168.0.11:1883,user=mqtt_user,pass=mqtt_password,retain=0,devices=rtl_433/debug
In the Logs it’s able to find my neighbour’s Acurite sensor:
[rtl_433] time : 2025-05-27 10:03:46
[rtl_433] model : Acurite-609TXC id : 74
[rtl_433] Battery : 1 Temperature: 21.3 C Humidity : 52 % status : 1 Integrity : CHECKSUM
As well as my PIR 433Mhz sensor (after I wave my hand in front of it):
[rtl_433] time : 2025-05-27 10:04:45
[rtl_433] model : Generic-Remote
[rtl_433] House Code: 20673
[rtl_433] Command : 135
[rtl_433] Tri-State : ZZ00100ZX0Z1
in RTL_433 Auto Discovery this is how the config is set up:
master: false
mqtt_host: 192.168.0.11
mqtt_port: 1883
mqtt_user: mqtt_user
mqtt_password: mqtt_password
mqtt_retain: true
rtl_topic: rtl_433/+/+/events
device_topic_suffix: ""
discovery_prefix: homeassistant
discovery_interval: 600
force_update: false
log_level: default
The topic went from rtl_433/+ to rtl_433/+/+/events after going back and forth trying to troubleshoot this with ChatGPT.
in MQTT Explorer this is how I have it set up to connect:
and this is all it’s able to find under RTL_433 in terms of topics:
The device there is the PIR 433 Mhz sensor, but it’s only showing availability (online and offline) and not the device info that shows the House and Command codes as shown above from the RTL_433 logs.
Chat GPT has me spinning around in circles and I’m sure there’s something I’m completely neglecting here.
Any tips would be greatly appreciated!
